Ken Buck[1] leads Jane Norton[2] by nine points in a poll paid for by his campaign and released Thursday, with 17 percent of Republican voters still undecided.

Ninety-one percent of Republicans[3] say they plan to vote in the primary, 52 percent have a favorable opinion of Buck and 45 percent have a favorable opinion of Norton, according to the poll done by Magellan Data and Mapping Strategies.

The interviews with 759 registered Republicans were conducted yesterday. The poll has a 3.5 percent margin of error.

Jane Norton spokeswoman Cinamon Watson called the poll incredible because it was paid for by Buck’s camp.

“It looks like Ken is trying to change the debate and move away from his childish comments and ethics charges,” she said. “This is a poll he paid for and not credible. We are very confident in our campaign, our momentum, and in victory.”

Buck and Norton continue to face off in debates across the state, including two today. The 9 News/Denver Post debate was taped this afternoon and will broadcast on YourShow on Sunday at 10:30 a.m. on MY20 and Comcast Channel 3.
